Missing Titanic Sub Highlights Dangers of Extreme Tourism

The story of the tourists lost on the dive to the Titanic is putting a spotlight on extreme tourism around the world. For the right price, just about anyone can go anywhere, including a vacation to the South Pole. From Mexico's Cave of Swallows, to cage diving among great white sharks, these hazardous trips are targeted at adrenaline junkies. However, there's a possibility extreme vacations can go tragically wrong. In 2019, 22 people were killed when an active volcano erupted in New Zealand.
